# ReqRes - **Website:** - **Primary alias:** `reqres.in` ## Description ReqRes is a hosted REST API platform for testing, prototyping, education, and building lightweight backends. Its free public API provides ready-to-use endpoints for users, resources, registration, login, and CRUD operations, with realistic responses and error cases. Developers can send requests without signing up or maintaining servers, making ReqRes useful for QA automation and tools such as Playwright, Cypress, and Postman. For projects that need persistent data, users can create an account and build a backend with an API key, custom collections, authentication, and request logs. The platform also offers sample data, stable schemas, and full CRUD functionality, plus options for higher request limits and team or company licences. Additional testing capabilities include deterministic responses, on-demand failure scenarios, and a Docker image for offline CI/CD use. ReqRes also provides a sandbox for AI agents, featuring seeded data, deliberate failure cases, simulated payment flows, and replayable activity logs. Its audience includes QA engineers, frontend developers, educators, founders, and agent developers who want to test or build without setting up and managing backend infrastructure. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Programming and Developer Software _(under Computers Electronics and Technology)_ - 🖥 Cloud Services and Computing _(under Computers Electronics and Technology)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idZqXyOYMq/w/1035/h/284/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1792103378259) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Black | #000000 | dark | | White | #ffffff | light | | Mountain Meadow | #10b981 | accent | ## Fonts - -apple-system — asset _(system)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
